+# Support for FAIR principles in openEO backends
+
+[FAIR principles](https://www.go-fair.org/fair-principles/) provide some guidelines when producing and sharing datasets.
+
+An openEO backend can make it easier to comply with these principles, by incorporating these principles in the implementation, so that
+users are automatically a step closer to generating FAIR-compliant open data. 
+
+These are a few examples that you want to look for as a user, or that a backend provider may want to implement:
+
+- *[F2 Rich metadata](https://www.go-fair.org/fair-principles/f2-data-described-rich-metadata/)* openEO backends generate STAC metadata, 
+  backends are encouraged to make it rich by including processing info, complete raster metadata, band information, etcetera.
+- *[R1.2 Detailed provenance](https://www.go-fair.org/fair-principles/r1-2-metadata-associated-detailed-provenance/)* In result metadata [derived-from](https://github.com/radiantearth/stac-spec/blob/master/item-spec/item-spec.md#derived_from)
+  links can link back to all input products to provide provenance.
+- *[R1.3 use of domain relevant metadata standard](https://www.go-fair.org/fair-principles/r1-3-metadata-meet-domain-relevant-community-standards/)* openEO generates STAC metadata, so this one is included by default.
+
+As openEO backends do not automatically publish the data you generate, there's also a number of principles that still require some attention, 
+but still, with data and metadata generated by openEO, you should get a headstart!
